Sergey Alyoshin fb995444b9 kobs-ng: test kernel version for redefines
kobs-ng failed to build with 2.6.36, because enum tested with #ifndef

mtd.c: In function 'mtd_open':
mtd.c:696:42: error: 'MTD_FILE_MODE_NORMAL' undeclared (first use in this
function)
mtd.c:696:42: note: each undeclared identifier is reported only once for each
function it appears in
mtd.c: In function 'mtd_set_ecc_mode':
mtd.c:896:43: error: 'MTD_FILE_MODE_NORMAL' undeclared (first use in this
function)
mtd.c:914:43: error: 'MTD_FILE_MODE_RAW' undeclared (first use in this
function)

Do kernel version test before enum redefines.

Newer kernel headers renamed mtd mode defines and no longer support
MEMSETOOBSEL. Allow code to work with both older and newer kernel
versions.
